The hydrocracking behavior of a C 4 –C 70 mixture of n-paraffins on a platinum/amorphous silica–alumina catalyst has been analyzed. The influence on the system behavior of operating conditions, i.e. pressure, temperature, H 2 /feed ratio and stream velocity, has been investigated by means of experimental data from a bench scale reactor, the last aim being the derivation of a proper model for the reaction system. Because of the high number of species involved, a model which takes into account pseudocomponents (lumped model) corresponding to the cuts of interest for the refinery has been considered. The obtained results show good agreement with experimental data.
